91. Which of the following governors is not spring controlled?

- Hartnell governor
- Hartung governor
- Wilson-hartnell governor
- Porter governor

92. Which among the following is not spring controlled governor?

- Pickering governor
- Hartnell governor
- Hartung governor
- Proell governor

93. The height of Watt’s governor is proportional to

- N (speed)
- N
^{2} - 1/N
- 1/N
^{2}

94. The sensitivity of governor is 0.28 the maximum equilibrium speed is 80 rpm and the mean equilibrium speed is, 70 rpm then the minimum equilibrium speed is

- 55
- 65
- 60
- 50

95. Sensitiveness of the governor is defined as

- Range of speed/mean speed
- Mean of speed/range speed
- Mean of speed × range speed
- 2 × Mean of speed/range speed
- Range of speed/(2 × mean speed)

96. Which among the following is pendulum type governor?

- Proell governor
- Porter governor
- Watt governor
- Hartnell governor

97. The sensitiveness of a governor is equal to

- ω/(ω
_{2}– ω_{1}) - (ω
_{1}– ω_{2})/ω - (ω
_{2}– ω_{1})/2ω - 2(ω
_{1}– ω_{2})/ω

where, ω_{1} = maximum speed, ω_{2} = minimum speed and ω = mean speed

98. For a given sleeve lift in governor, the sensitivity

- decreases as speed decreases
- increases as speed decreases
- increases as speed increases
- remains unaffected
